What causes psychopathy? This has been a major concern for many researchers. Research on psychopathy has sparked a debate that has been existent for years, which is the nature versus nurture debate. The proponents of both sides have each put forward credible evidences to support their positions. Proponents of the nature theory believe that psychopathy is innate. They hold the belief that psychopaths are born with the disorder. Hence, psychopathy is influenced by biological and hereditary factors. In contrast, opponents of the nature theory believe that a person’s personal experiences are the reasons for his or her exhibition of psychopathic characteristics. That is, a person with a defective childhood has a very high probability of displaying …show more content…
Nature theorists believe that psychopathy is a disorder of the brain. This disorder can either be considered to be physical or chemical. Physically, the brain of a psychopath is structured differently. The amygdala in the brain of the psychopath is malformed. That is, it is either enlarged or too small. According to Parker (2015), “[t]he amygdala is the section of the brain that processes our emotional reactions and helps us with decision making”. A malfunction in this area of the brain leads to impaired judgment due to poor decision making. It also results in an impairment in processing the emotions of others (Parker, 2015). These are well known characteristics of psychopaths. Furthermore, there are speculations by researchers that psychopathy could also be as a result of a dysfunction in the prefrontal cortex. The prefrontal cortex is “an area of the brain that is believed to be important to reasoning, inhibition of behavior, social emotions, empathy, attention, and executive functions” (Kosson, 2014). Psychopaths lack emotions, empathetic skills, and so on. However, the majority of the studies conducted to examine this have been with violent offenders rather than psychopaths (Blair, 2003) which reduces its credibility as an
Nature versus nurture has been argued in attempt to understand how criminals behave. The theory of what influences psychopath and serial killers’ violent and destructive pathways has not been agreed on till this day. Criminals such as psychopaths and serial killers have been researched for the past two decades. Scientists have found that genetics is a determining factor of who becomes a serial killer. It is important to understand the determinants involved within a serial killer, because if these social and environmental causes are discovered, they can be altered and controlled to reduce crime (Lykken, 1993). With more studies, we would therefore prevent mass murders and could assist in significant reductions of crime within society.
Krafft-Ebing (1886) found that the serial killer had been through cruelty of animal; enjoy the torture and the pain of their victim during his or her childhood period. Moreover, the mothers of these serial killers were most of time working or doing other things and usually the father were absent. These children experience rejection and lack of attention, therefore, this child grows up having low self-esteem. Research show that adults that gone through abuse and violent behavior during their childhood were three times more likely to become violent as adult more than the non abused adults (Dutton & Hart, 1992).
Identifying the mystery of the psychopath can prove to help the them and the general public. Early awareness of the common psychopaths among us will reduce the impact on society. Further research is still needed to better help the psychopath and the general population.
The case of whether serial killers are born with the lust to kill or if they are truly victims of their environment has been a hot debated question by both psychologists and the FBI today. A serial killer is traditionally defined as one that kills 3 or more people at different times with “cooling off” periods in between kills. Both psychological abuse as a child and psychological disorders are to blame for the making of a killer. The nature vs. nurture debate is best applied to the mysterious behaviors and cases of serial killers and their upbringing and environment. Nature is the genetic and biological connections a person has, personality traits, and how genetic make-up all relates to a killer. Nurture is examining the upbringing and environment that a person is around that affects what a person becomes. In some cases however, the effects of only upbringing or only biological problems were the reasons certain serial killers committed crimes. Although there is no definitive answer to what plays the bigger role: nature or nurture, they both are contributing factors that make a serial killer. These deviants of society are afflicted with problems in either their upbringing or have psychological disorders, and are able to blend into our everyday lives with no apparent differences, yet they wreck havoc through their unremorseful killings.
I agree that psychopaths can exhibit learned knowledge of morality; however, I believe that their moral indifference can be attributed to the brain abnormalities and behavioral deficits. Because these deficits are uncontrollable with respect to the individual, pulling from Levy’s (2008) argument, psychopaths are not responsible for their lack of motivation regarding morality. Additionally, their diminished attention span and inability to gage consequences also play a role in their moral indifference. A psychopath may logically understand that their actions are wrong, but because of a shortened attention span they cannot focus on the many long-term consequences of their actions (Maibom 2005). Thus, they are not responsible for their actions because of a plethora of abnormal brain and behavioral
There have been many studies on what behaviors constitute psychopathy. Various Studies have shown that an individual’s behavior must include actions such as hostility to animals or people, ruin to possessions, dishonesty or larceny, and grave violations of rules, as well as a clinically defined impairment of an individual’s social, educational, or employment-related purposes. In order for an individual to be found to be presenting such a disorder, he or she must present with a minimum of at least one of the previous mention behaviors in the past six months, or three plus in a twelve-month timeframe (Mueller III, 2012). Individuals present with psychopathic propensity or psychopathy have a tendency to have a decreased aptitude to name apprehensive facial expressions and a frightened vocal change. An out of...
Psychopaths literally feel nothing when it comes to violence or fear. Levy studies show that the emotional sectors of the brain are damaged. This makes them dangerous. They can not see that something is hurting or they are hurting someone.
Psychopathy is a mental disorder in which an individual manifests amoral and antisocial behavior, lack of ability to love or establish meaningful personal relationships, extreme egocentricity, failure to learn from experience, etc. Psychiatrist look for certain traits, of which there are five main ones, when trying
Serial killers are defined to “be driven by instinct and desire to kill.” In a study done in 2000, Dr, Richard Davidson says, “people with a large amount of aggression – in particular people who have committed aggressive murders or have a social disorder – have almost no brain activity in the orbital frontal cortex or the anterior cingulated cortex while activity in the amyglade continued perfectly. The orbital frontal cortex and the anterior congulated cortex control emotional impulses while the amyglade controls reactions to fear.” Davidson concludes his research claiming that although environment can and will affect a serial killer’s thoughts, it is a killer’s genetic makeup that inevitably creates murderous thoughts.
According to the Federal Bureau of Investigations website, psychopathy has been described as the single most important clinical construct in the criminal justice system. It goes on to say that the need to understand psychopathy cannot be overstated (FBI, 2013.) From environmental influence to biology, psychopathy can be looked at from several different angles. This paper examines current thinking about how the brain and its structures contribute to psychopathy.
They conducted MRI’s on 40 inmates at the Wisconsin prison. The results showed that in the case of psychopaths there is significantly less communication from the prefrontal cortex (ventromedial) area of the brain to the amygdala. The brain scans of criminals of opportunity’ brain show a close connection between the part of the brain that is responsible for overseeing fear and the part of the brain the controls emotions. This indicates, the latter are remorseful and surrender to the police. (Nistor-Lung & Neagu, 2013). All of these studies yield the same results that the amygdala plays a crucial role in the mind of a serial killer versus a normal human being. Serial killers lack the ability to perceive and understand their emotions and others emotions. This is precisely why serial killers feel no remorse after their killings, while a normal human being
A child or an adolescent being diagnosed with psychopathy is a controversial concept and yet there are a number of studies that purport to assess psychopathic traits within these groups. This has stemmed from evidence that key symptoms of psychopathy (at least when looking into the histories of adult psychopathic patients) have been indicative of an early onset with symptoms beginning in childhood or early adolescence. (Johnstone & Cooke, 2004). Psychopathy, at least in adults, is a viable construct and is often indicative of criminality, violence, substance abuse and results in decidedly poorer responsivity to treatment and as such highlights the importance of recognizing these early symptoms and planning intervention and treatment strategies. (Johnstone & Cooke, 2004; Skeem, Monahan, & Mulvey, 2003; Hempill, Hare, & Wong, 1998; Salekin, Rogers & Sewell, 1996).
Over the years, the theory has evolved into today’s foremost biological crime theory. The theory takes into account genetics and disorders that may be inherited. One example of a disorder that is genetic is antisocial personality disorder. This specific disorder is accompanied by a variety of side effects, some of which may result in psychopathic or sociopathic behavior. Psychopathic and sociopathic behavior specific to this example would be murder. Jeffrey Dahmer, for example, was an individual that participated in seventeen murders over a span of thirteen years. Although Dahmer was not able to plead insanity, he still had a severe mental disorder that may be partly to blame for some of his actions. Biological disorder is often difficult to back up due to the fact that many disorders are also based on nurturing
The question of whether or not man is predetermined at birth to lead a life of crime is a question that has been debated for decades. Serial killers are made not born; it has been demonstrated that a man 's initial years are the most vital years. A youngster 's initial couple of years is a period of experimentation, a period to make sense of things for themselves, a period to set up the bits of the riddle. Like a newborn child, the mental health is reliant on its environment. A youthful youngster 's mind resembles a wipe; it gathers data through perception. The surroundings of a serial killer as a little child can enormously impact the way he or she will go about his or her life and his or her style of murdering. Certain experience, for example, youngster misuse, divorce, liquor misuse, tyke disregard, as well as medication misuse, can be negative to the advancement of a little child. Numerous serial killers were illegitimate kids. Due to their childhood and early backgrounds, serial killers swing to crazy murdering frenzies.
While child abuse does not always result in a serial killer, the aftermath of the neglect and abuse is unforeseeable and can have many alternate routes. The researchers were trying to answer the question of if there was a common factor that many or all serial killers shared that could have attributed to their psychological issues. From the research gathered, it would appear that child abuse is a common factor, however it is not guaranteed that all serial killers experience child abuse and not all children that experience abuse will become serial killers. Some problems posed with this research is that an extensive amount of the information obtained was from an unconnected third party, therefore the truthfulness of the information must be scrutinized. Also, some criminals may lie about their past. Some may say that they were abused to have an explanation for their heinous crimes, or some may downplay their past because they do not wish to disclose vulnerable aspects of their life. In all, the child abuse among lust serial killers could be considered to be a factor in their murderous actions. It is warned, however, to not generalize these findings to all serial killers, as the information gathered was determined off a group of lust serial
